Description
UNITED STATES PATENT OFFICE.-
L. D. WALTER, oF FORT PLAIN, NEw YORK, AssIGNoR To JOHN L. YDAYTON vANDy s. KELLOGG. y y
DRILL FOR DNTISTS, &C.
Specification of Letters Patent No. 5,121,1datedv1VIay 15, 1847.
To all whom t may concern.'
Be it known that I, LORENZO D. WALTER, of Fort Plain, in the county of Montgomery and State of New York, have invented a new and useful Machine, called a Spring- Drill, for theUse of Surgeons and Dental Practitioners and Also for Drillingy Iron, Steel, Brass, Ivory, Wood, &c.; and I do hereby declare that the following is a full, clear, and exact description of the const-ruction and operation of the same, reference being had to the annexed drawings, making a part of this specication, in whichy Figure' 1, is a perspective view; Fig. 2, another view of the same; Fig. 3, a transverse section; Fig. 4, the drill stock drum and arbor; Fig. 5, the mainspring; Fig. 6, the mainspring barrel; Fig. 7, the ferrule and sheath; Fig. 8, the string and knob by which the machine is worked; Fig. 9,.the steel bed piece in which runs the pivot of the drill stock; Fig. 10, the screw which closes the magazine in the end of the handle; F ig.y 11, the 'small screw which holds the ferrule upon the handle; Fig. 12, the drill point and4 Fig. 13 the head of the mainspring vbarrel.
The handle of the machine is made of ivory, wood, or any suitable material, of any convenient size or shape, with a hole drilledy through it from end to end, for t-he admission of the bed piece, Fig. 9, and the pivot end of the drill stock Fig. 4.
The bed piece is situated about in the center of the handle, as seen letter C, Fig. 3,
with a hole in the center of one end for the,
pivot of the drill stock to run in; see Fig. 9, letter A. Between the bed piece and the screw, Fig. 10, in the end of the handle is a space, or magazine, for containing drill points, see letter A Fig. 2. The mainspringV barrel is. made of brass, or other suitable metal see Fig. 6. It is fastened on to the end of the handle as seen in Fig. 3 letter A, by means of a rivet, which barrel incloses the mainspring Fig. 5. The head of the mainspring barrel has a hole in it, letter A to admit the arbor on the drill stock, Fig. 4, letter A. On the inside of the mainspring barrel 1' is a small hook, similar to the hook letter B on the arbor, let-ter A, Fig. 4, on which the end of the mainspring letter A, Fig. 5, catches.
The mainspring, Fig. 5, is similar to the mainspring of a watch, of any convenient .3, letter B.
The drill stock is made of steel, Fig. 4. Ony one end is the pivot letter C, which runs in the hole in the end of the bed piece Fig. 9. In the other end, is a hole, letter D, in which to insert the drill point, countersink, trepan', or any instrument requiring a rapid circular motion. On the drill stock is fastened the arbor letter A, and the drum, letter E. In the drum is a hole letter F, in which the string is fastened by a knot, which works the machine. The string winds on the drum, and the mainspring on the arbor. Near the end, of the drill stock is afhole letter G to admit an instrument to crowd out the drill point. The ferrule and sheathpare made of silver, Fig. 7, and cover the mainspring barrel, drum, and a portion of the drill stock as far as the hole, letter G, Fig. 1.- The sheath being to prevent'the stock turning upon the lip when used in the mouth. In the ferrule is a hole letter A, through which runs the string with which the machine is worked.
lfastened on to the drum, Fig. 4, letter E, in
the hole F, by the knot on the end of the string, and is wound on the drum, when the machine is not worked. The knob is of ivory or other substance, and has a hook in one endin which-the other end of the string is fastened.
The screw, Fig. 11, fastens `the ferrule upon the mainspring barrel as seen in Fig. 2 letter B. The drill point is made of steel as seen in Fig. 12, and Ais inserted in the end of the drill stock vat letter D, Fig. 1.
Fig. 13,\is the head of the mainspring barrel, which sets into the barrel and can be t-aken out at pleasure.
The operation of the machine is as fol'- lows: The string is fastened to the drum, as above described; the other end is passed through the holein the ferrule and. fastened to the knob. The end of the drill stock marked C, is then inserted into its place in the handle, with the pivot in the bed piece, the mainspring hooked on to the arbor and Size, according to the use lto which the :ma-v l l the ferrule put in its place. Thestring, be'- l Wound around the arbor which gives the ing unwound, is pulled through the hole in machine greater power. the ferrule its full length-then by holding What I claim as my invention and desire 15 the handle in the right hand and the ferrule to secure by Letters Patent is-` in the left, keeping the errule stationary, The Combination of the mainspring pulley and turning the handle toward the body, the and cord, with the drill, for the purposes of string is Wound upon the drum and the drilling, countersinking, trepanning, &o.,
substantially as herein described.
LORENZO D. WALTER.
Inachlne is ready for use. By pulling the string by the knob and letting the spring react the machine is Worked. By turning the handle once, or partly, around, after the string is Wound up, the spring is strained or Witnesses:
